All changes of directions should be pre-fabricated leaving only butt welding for the field. If installing in an expansion joint, keep centre bulb unembedded to allow it to accommodate movement as designed. It is important that all waterstops are held securely during the concrete pour and that the concrete is properly compacted to remove voids and porous areas. Centrebulb installation Position waterstop in joint as indicated on drawings. Centre the waterstop on the joint, with approximately one-half of waterstop width to be embedded in concrete on each side of the joint. Allow clearance between waterstop and reinforcing steel of a minimum two times the largest aggregate size. Prevent pockets and air voids caused by aggregate bridging. Secure waterstop in correct position at 300 mm maximum centres with tie wire to adjacent reinforcing steel. Centre-tocentre spacing may be increased upon written request and approval from Engineer. Carefully place concrete without displacing waterstop from proper position. Thoroughly and systematically vibrate concrete in the vicinity of the joint and to maximise intimate contact between concrete and waterstop. After first pour, clean un-embedded waterstop leg to ensure full contact of second concrete pour. Base Seal / Rear Guard installation Position waterstop in joint as indicated on drawings. Centre waterstop on joint, with approx. one-half of waterstop width to be embedded in concrete on each side of joint. For horizontal applications where an already stable support exists, Base Seal/Rearguard profiles generally require no fixing as they are laid centrally along joint being formed. For vertical applications Base Seal/Rearguard profiles can be nailed through outer flanges directly onto formwork. Carefully place concrete without displacing waterstop from proper position. Thoroughly vibrate concrete in vicinity of joint to maximise intimate contact between concrete and waterstop. After first pour, clean un-embedded waterstop leg to ensure full contact of second concrete pour. Welding instructions Thermoplastic Vulcanizate Waterstop — The joining of straight lengths shall be done by squaring the ends to be joined and using a thermoplastic welding iron with a nonstick surface specifically designed for waterstop welding.The correct temperature (210°C to 220°C) shall be used to sufficiently melt without charring the waterstop. The welded area, when cooled, shall show no signs of separation, holes, or other imperfections when bent in an angle by hand. Estimating EarthShield Profile Width Roll length Centrebulb: 150 mm 230 mm 15 m 15 m Base Seal / Rear Guard: 230 mm 15 m Factory made intersections, Retro Fit and Dumbell waterstops are available on specific order. Normal stocked products are the 230mm Centrebulb and 230mm Rear Guard profiles, other sizes are available on request. Earth Shield TPV/TPER
